An analytical investigation of induction motor behavior in the case of flicker occurrence using finite element method

This paper investigates induction motor modeling parameters and its behavior under flicker conditions using finite element method (FEM). Nowadays, increasing usage of power electronics and harmonics-made loads has made power quality a challenging issue. Therefore, the behavior of electrical elements (e.g. motors), under the power quality conditions, needs to be studied. Despite definite induction motor’s parameters, there are several defeats in the modeling procedure of the motor. Considering all of the parameters of the motor, it may make the analysis complicated incongruously. To ease the problem, numerical methods is employed. In this paper, an induction motor is modeled completely. The machine is modeled by 2D method and the effect of excitation system is seen. The effect of the motor winding is studied, and the results are compared with other models. In order to earn accurate results, some modifications in 2D modeling are applied. The motor is subjected to flicker condition. All of obtained results are simulated by MAXWELL software.
